FLUSHING APPARATU S.

Application, filed June 17,

a desired quantity of water to water closets v or the like.

It is a further object of my invention to provide a flush tankwhich may be placed at any desired elevation, and which may comprise an outer box in which no water need stand, and whose body is provided with only one opening; and in my preferred construction I employ also an inner tank or receptacle which may be pivotally mounted upon an inlet pipe, or upon parts connected therewith.

It is a further object of my invention to provide a device of the character referred to which may dispense with all floats and float-controlled valves; and for this purpose I prefer to so suspend my inner tank or receptable that, when a suitable quantity of water or other liquid shall have been delivered thereto, the weight of. this liquid shall serve to close the inlet valve; and in thisconnection I prefer to provide means for pivotingsaid inner receptacle alternatively at various distances from a fulcrum and I find it advantageous to provide also a pivoted and adjustable counterweight tending to open said valve whenever the-,mentioned inner receptacle is emptied, my preferred construction being such that the mentioned counterweight shall-retain the inlet valve open until the desired quantity of water or other liquid shall be delivered therethrough.

Other objects of my invention will appear from the following description of a preferred embodiment and the appended claims, taken in connection with the accompanying drawings, in which- Figure 1 is an elevation with parts broken away. This figure shows a cover which may optionally be omitted.

Referringin detail to, the parts of that embodimentof my invention whichI have selected for illustration, 1 is an outer box, which. should bev water-tight, but whichv is shown as provided with buta single outlet 2 below the water line Extending into this. box, or outer receptacle, from above or from, any. elevatedpoint, I may provide an inletpipe, 2; having a valved delivery such, as, the gooseneck siphon.valveorganization 3,.

shown as comprisinga return bend 4 and a delivery pipe 5, between which is' interposed'a central member 6 provided witha seat for the vertically movable valve 7 and provided also with upstanding arms 8 and 9, respectively provided with apertures to receive pivot pins 10 andll.

The end of the inlet pipe 2, carrying the associated parts above referred to, may be supported in any suitable way, and for this purpose I may secure a bracket 12, or the like, by any convenient means, such as the screws 13. In order that water need not stand in the outer box 1, and in order to use the weight of a desired quantity of water as a means to control the inlet valve 7, I prefer topivot the'inner tank or receptacle 14 by means of a rod 15 upon one end of a lever 16 pivoted on the pi-nlO and passing through or otherwise adapted to actuate thevalve 7. i

The pivot rod 15, extending to the lateral walls of the inner tank 14, may advantageously occupy a substantially contral position in the upper part of the outer box 1, as shown in the drawings; and any suitable means may be provided to tilt and thereby empty the contents of the inner receptacle 14 into the box 1, in order that a desired quantity of water may be promptly -delivered through the outlet pipe 2. To effect this delivery I prefer to employ an ordinary pull cord or chain 17 which may be providedwith a handle 18, extending over a pulley 19, and which may be secured by means such as the perforated lug 20 upon the outer surface of the receptacle 14. It will be understood that, when this construction is employed, a pull upon the handle 18 will sufiice to tilt the receptacle 14 into the weight of water which may again accumulate within the receptacle 1 1, as soon as the handle 18 is released and the receptacle 1 1 is permitted to return to its receiving position under the action of gravity, will tend, in turn, to close the valve 7 and will complete the closure thereof whenever a sufficient quantity of water shall have been; delivered into the receptacle 14.

It will be obvious that the satisfactory operation of my flushing apparatus, as thus far described, will depend upon several factors, such, as the. pressure at which water is delivered through the pipe 2, the weight of the receptacle 14, and the quantity of water which it is desired to deliver, at one time, through the outlet pipe 2. Accordingly, I find it important to provide means, and preferably adjustable means, opposing the action of gravity upon the tank 14 and the contents thereof; and my preferred construction for the purpose indicated comprises a lever 21 pivoted upon the pin 11, and connected by the link 22, pivoted upon the rod 15 and secured to the lever 21 by pin 23, the opposite end of the lever 21 being provided with an approximately horizontal arm 25, carrying the adjustable counterweight 26.

From the foregoing description it will be obvious that although the weight of the inner receptacle 1 1 and its contents must always tend, by their downward pull upon the movable end of the lever 16, to close the valve 7, the effect of the weight 26, upon an arm extending from the substantially parallel lever 21, is such as to produce an opposite or upward pull by means of the link or links 22, upon the mentioned lever 16, thereby tending to open the valve 7. The rod 1.5 may alternatively be seated in any one of the openings 27, extending through the lever 16 and, the weight'26 being adjustable upon the arm 25, it will be apparent that, by suitable adjustments, the various elements of my device may be so inter-connected as to adapt the same to use under a wide variety of conditions and permit of the prompt delivery of either a very small or a very considerable quantity of water or other liquid whenever the inner receptacle 14: shall be tilted.

It will also be obvious that the construction which I have described is comparatively simple and not unduly expensive to construct; and that it is not in the least likely to get out of order or to permit a continuous leakage or waste of water. A cover 28 may be employed or omitted as desired.

Although I have herein described but one embodiment, it will be understood that various features thereof might be independently employed, and also that various modifications might be made therein without.

departure from the spirit and scope of my invention as the same is indicated above and in the following claims.

What is claimed is:

1. A flush tank comprising an outer box having a drain, an inlet pipe leading into the top of the box and extending downwardly, a return bend secured to the inlet pipe, a fitting extending upwardly from the return bend, a discharging pipe extending downwardly from the fitting, a vertically movable valve in the fitting and provided with upstanding arms, one arm being longer than the other, a lever pivoted to the short arm for operating the valve, a long pivot rod extending through the movable'end of the lever, a secondary receptacle connected to the ends of the pivot rod and supported thereby, means for tilting the secondary receptacle to empty the receptacle, a link connected to the pivot rod, a second lever pivotally mounted upon the long arm and connected to the link, a rod extendingfrom the second lever, and a weight adjustably mounted upon the rod so that when the secondary receptacle is empty the weight will open the valve and so that when the secondary receptacle is sufficiently filled the weight of the receptacle and water will counter-balance the adjustable weight and close the valve. 7

2. In a flush tank construction a supply pipe having an upwardly extending discharge end, a fitting upon the upper end of the supply pipe, a discharge pipe leading downwardly from the fitting, a valve in the fitting, a lever pivotally mounted to operate the valve, a secondary receptacle pivotally connected to the movable end of the lever, a link extending from the pivot, a second lever pivotally connected parallel with the first lever and connected to the link, a rod extending from the second lever, a weight adjustably mounted upon the rod, and means for tilting the secondary receptac e.
